Hey! Look what I found online.
In general, it makes the angiosperms more efficient in pollination and, therefore, in producing seeds. Most angiosperms have perfect or bisexual flowers, that is, both the male and female reproductive organs are borne on the same flower while these are separated in the gymnosperms. In the conifers which are gymnosperms, thousands of pollen grains will be needed to pollinate one female. The pollens are carried by the wind and having one pollen land exactly on the stamen is quite an impossibility.
<span>Many angiosperms have colorful petals. This attracts the insects and birds. As they move from one flower to another, they deposit the pollens on the stigma of another flower. The nectar that angiospermous flowers produce and the aroma emitted play the same role.</span>
the answer is no. You need the two torques to equal in order to lift something. That is 9 X 2 = lifting torque and 9 X 3 = lifted torque.
As you can plainly see 18 < 27; so you cannot lift that 9 N weight located 3 meters from the fulcrum.
D. Bounce four is the answer
Stratus is the cloud which forms near the ground.
Stratus is referred to as low-level clouds. They are being characterized by the horizontal layer which has a uniform base. Stratus is used to describing features and hazy.
Stratus clouds do produce a small amount of show or light drizzle and they are above ground. It is formed when a sheet of moist air, warm lifts off the depressurizes and ground and it follows lapse rate.
This leads to relative humidity to increase because of adiabatic cooling.
